How to convert for-in loop into foreach in Swift? – Ios swift

I have one for loop where I found index in repeating hence I want to convert into foreach loop.

for (key, _) in details {
    let product = product
    details[key]?.title = product.first?.name ?? ""
    details[key]?.amount = Double(product.first?.prices ?? 0.0)
}

I tried this as below but still here details[key]? is repeating

details.forEach { key, value in
   let product = product
   details[key]?.title = cartProduct.first?.name ?? ""
   details[key]?.amount = Double(product.first?.prices ?? 0.0)
}

May I know, how to convert this into foreach in Swift so that I don’t need to write [key] every-time.

    You can do it this way:

        details.forEach { _, value in
        value value = value // Add this if your `value` is a struct
        let product = product
        value.title = cartProduct.first?.name ?? ""
        value.amount = Double(product.first?.prices ?? 0.0)
    }

    let product = product
    mutableProduct.value.title = cartProduct.first?.name ?? ""

}
